A highly stable intubation thruster for cardiovascular surgery

Abstract

The invention discloses a high-stability cannula impeller for cardiovascular surgery. The impeller comprises a first fixing block, a first mounting cavity is formed in the first fixing block, and a first rotation rod and a second rotation rod which are horizontally arranged are rotatably installed in the first mounting cavity; a first gear and a first bevel gear are fixedly arranged at the outer sides of the rotation rods, a second bevel gear is fixedly arranged at the outer side of the second rotation rod, and the first bevel gear is meshed with the second bevel gear; one end of the second rotation rod extends to the outer portion of the first mounting cavity, a second fixing block is arranged at the top of the first fixing block, and a second mounting cavity is formed in the second fixing block; a horizontally-arranged threaded rod is rotatably arranged in the second mounting cavity, one end of the threaded rod extends to the outer portion of the second mounting cavity, a second gearis fixedly arranged at one end of the threaded rod, and one side of the second gear extends into the first mounting cavity. The high-stability cannula impeller for the cardiovascular surgery is novelin structure and convenient to use, a cannula can be accurately and stably pushed, and the difficulty of surgical intubation is reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a high-stability intubation propeller for cardiovascular surgery. Background technique [0002] In heart or great vessel surgery, it is often necessary to insert surgical catheters in the human body, and these catheterization operations rely entirely on medical staff to insert the catheter into the surgical incision. This manual operation has high requirements on the operator, and it is difficult to grasp the stability and accuracy of the hand-held intubation. Chinese patent 2012102651582 discloses a "cardiovascular surgery intubation clamp", which can be used to clamp the end of the intubation tube during the operation, and the operation of holding the fixation frame during the intubation process can improve the intubation operation to a certain extent accuracy and stability. But this clamp can only play the role of fixing the intubation and being convenient for ha...

Problems solved by technology

But this clamp can only play the effect of fixing the intubation and being convenient to hold, can't realize the action of advancing intubation, still relies on the operator to move the arm to realize the operation of intubation in the intubation operation, for the unskilled doctor, operation It is very difficult to move the arm accurately and steadily during the
